Ask quick side questions without polluting your main chats. GPT Master adds a Side Chat panel inside chatgpt.com: highlight any reply and the answer arrives in a separate right panel.

Updated

Highlight a reply, then ask in the right panel. Main chat untouched.

Quick answer

ChatGPT does not have a built-in way to ask a sub-question about a single message without changing your main chat. Asking inline shifts the conversation off course; opening a new chat loses context. Side Chat solves this by opening a separate panel on the right with the highlighted text attached as context, so the side question is answered there and your main chat keeps its trajectory.

What this looks like in practice

Example: using Side Chat during a market-research synthesis

A market researcher is mid-conversation with ChatGPT, working through a long synthesis of three industry reports. Two-thirds of the way down a reply, ChatGPT drops in an acronym (TAM/SAM/SOM) the researcher wants double-checked before quoting it in the deliverable. Asking inline would derail the synthesis; the next reply would explain TAM/SAM/SOM instead of continuing the analysis. Opening a new chat would lose the report context entirely. With Side Chat, the researcher highlights the acronym and asks for a one-paragraph refresher in the right panel. The main chat, untouched, picks up exactly where it left off.

Frequently asked

Questions people have before they install

These questions cover fit, workflow, and what to expect before installing GPT Master, so people can understand the feature in practical terms before clicking through to the Chrome Web Store.

What does Side Chat send when I ask a question?

Side Chat sends the text you highlighted, the full ChatGPT reply it came from, and the user prompt that produced that reply. Earlier messages in your main chat are not sent. The side question is scoped to that single exchange.

Where do side conversations live?

Side Chat conversations live in the right panel of the extension. They don't appear in your ChatGPT sidebar or your ChatGPT account history because Side Chat runs separately from ChatGPT's own conversation system.

Does Side Chat use my ChatGPT account or count against ChatGPT's rate limits?

No. Side Chat runs through GPT Master's own API, not through your ChatGPT account. Asking side questions doesn't touch your ChatGPT message cap or rate limits.

Is Side Chat free?

Yes, with a weekly cap on the free tier. Heavy users can lift the cap with GPT Master Pro from inside the extension.
